    On my iPad Air 2 with iOS 9.0 and iOS 9.0.1 sucks. I have the same settings set as I did in iOS 8.4.x. With iOS 8.4.x I could go about a week with heavy usage, Kindle, weather apps, Facebook. Since I upgraded to iOS 9.0 and 9.0.1 I'm lucky to get 2 days with the same usage. I have background app refresh turned off on all apps. I close every app out except Kindle and I do have background app refresh shut off for the app.

    My iPhone 6 and 6S seem to get the same battery life as they did in iOS 8.4.x. I just read about the WIFI Assist switch and I turned it off on both my iPhone 6S and my iPad Air 2. So I'll see if that helps.

    Okay. Good luck. In the meantime, try restoring the device and setting it up as new. Take care

    I think I need to go back to 8.4.x. I charged my iPad last night and down to 47%. With 8.4.x I could get 4 full days out of the battery.iPad Air 2 and iOS 9 battery life-imageuploadedbyimore-forums1443484720.979835.jpg

    If I do a restore using a backup from before iOS 9 was released will that also restore my iPad to iOS 8.4.x? BTW I have all of the "Background Refresh" items shut off.

    there is no way to restore your ios to a previous version. try rebooting the ipad and if that doesn't work wipe it and restore it with your latest backup. my ipad gets great battery life in ios 9

    Welol last night I put my iPad away with the battery indicating 30%. When I started using it this AM it was still at 30%. After using is fairly heavily, Kindle, 1 game, Facebook using a cellar connection which is very weak, for about 2 hours it is still at 30%. So I think for reason the battery indicator may need to be "calibrated". I'm going to run it down until the battery indicates less than 10% or the iPad shuts down. I'll then recharge it and see what happens.
